Let me tell you, celeriac might not win any beauty contests, but it’s the hidden superhero of the vegetable world! This gnarly, humble root doesn’t often get a chance to shine, but today? It’s taking center stage. Roasted celeriac steaks are hearty, full of earthy flavor, and oh-so-satisfying. Add a velvety tarragon mustard sauce and a crunchy crispy shallot topping, and suddenly, this understated veggie transforms into a dinner-table star. If you’ve been searching for a dish to surprise and impress (even yourself), this is it—because who knew a root vegetable could taste this good?

Roasted Celeriac Steaks With Tarragon Mustard Sauce And Crispy Shallot Topping Recipe

What sets this recipe apart is its balance of flavor and texture. The celeriac, when roasted, has this gorgeous caramelized crust with a creamy, tender center that’s comfort food at its finest. But the magic lies in the toppings: the tarragon mustard sauce is tangy, rich, and herbaceous, bringing a hint of French-inspired elegance. And then there are the crispy fried shallots, golden and crunchy like bits of savory confetti sprinkled atop the steaks. Together, these elements hit salty, sweet, tangy, and umami notes—your taste buds won’t know what hit them! Not to mention, it’s a great way to spotlight celeriac, an underused vegetable that totally deserves its moment in the limelight.

Now, let’s talk tips to ensure this dish is next-level amazing! First, make sure to peel the celeriac thoroughly; that tough outer skin can’t be roasted away. Cut the steaks about an inch thick—too thin and they’ll dry out, too thick and they might not cook evenly. As for the crispy shallots, don’t rush them; slow frying at the right temperature is the secret to golden perfection without burning. And when whisking up the tarragon mustard sauce, a splash of white wine or a vinegar of your choice can add just the right pop of acidity. Trust me, these little details make all the difference.

Whether you’re looking for a sophisticated main for a plant-based dinner or a side dish that’ll steal the show, this recipe has your back. Serve these celeriac steaks with a fresh green salad, roasted potatoes, or even over a bed of lentils for a hearty, protein-packed meal. Want to mix it up? Swap the tarragon for dill or parsley, or try topping the steaks with crispy leeks instead of shallots. Your kitchen, your rules. So what are you waiting for? Grab a celeriac and let’s get roasting—you’re about to fall head over heels for this unassuming root!

Ingredients

  • 1 large celeriac (celery root), peeled and sliced into 1-inch thick steaks
  • 2 tablespoons olive oil
  • 1 teaspoon sea salt
  • 1/2 teaspoon freshly ground black pepper
  • 2 medium shallots, thinly sliced
  • 1/4 cup all-purpose flour
  • 1/4 cup vegetable oil (for frying)
  • 2 tablespoons Dijon mustard
  • 1 tablespoon whole-grain mustard
  • 1/4 cup fresh tarragon, finely chopped
  • 1 clove garlic, minced
  • 1/2 cup heavy cream
  • 1 teaspoon lemon juice
  • 1/2 teaspoon honey (optional)

Instructions

  1. 1

    Preheat the oven to 400°F (200°C) and line a baking sheet with parchment paper.

  2. 2

    Brush both sides of celeriac steaks with olive oil and season with sea salt and black pepper.

  3. 3

    Place the celeriac steaks on the prepared baking sheet and roast in the oven for 30–35 minutes, flipping midway, until golden and tender.

  4. 4

    While the celeriac is roasting, prepare the crispy shallot topping. Toss the sliced shallots in the all-purpose flour to coat evenly.

  5. 5

    Heat the vegetable oil in a skillet over medium heat. Fry the floured shallots in batches until golden brown and crispy, about 2–3 minutes per batch. Transfer to a paper towel-lined plate and set aside.

  6. 6

    In a small saucepan over medium heat, combine Dijon mustard, whole-grain mustard, chopped tarragon, minced garlic, and heavy cream. Cook, stirring continuously, until the sauce thickens slightly, about 3–4 minutes.

  7. 7

    Add the lemon juice and honey to the sauce and stir to combine. Adjust seasoning with salt and pepper, if needed.

  8. 8

    Remove the roasted celeriac steaks from the oven and arrange them on a serving platter. Drizzle with the tarragon mustard sauce and sprinkle the crispy shallots on top.

  9. 9

    Serve immediately as a flavorful and elegant main course.

Frequently Asked Questions

Q: Can I substitute celeriac with another vegetable?

A: Yes, you can substitute celeriac with other sturdy root vegetables like rutabaga, turnips, or even thick slices of cauliflower. Keep in mind that cooking times may vary depending on the vegetable, so check for tenderness as you roast.

Q: What can I use instead of heavy cream in the sauce?

A: You can substitute heavy cream with coconut cream or cashew cream for a dairy-free option. Alternatively, half-and-half or Greek yogurt (thinned with a little water) can also work, though the sauce may have a slightly different texture and flavor.

Q: How do I store leftovers, and can I reheat them?

A: Store leftover celeriac steaks and sauce separately in airtight containers in the refrigerator for up to 3 days. Reheat the steaks in a 350°F (175°C) oven for 10–15 minutes until warmed through. Gently reheat the sauce in a saucepan over low heat, stirring occasionally to prevent it from separating.

Q: My shallots didn't turn out crispy. What could have gone wrong?

A: If your shallots are not crispy, it might be due to too low of an oil temperature or not frying them in batches. Make sure the oil is heated to medium (around 350°F or 175°C) and fry the shallots in single-layer batches. Overcrowding the skillet can lower the oil temperature and lead to soggy results.

Q: Can I make the sauce ahead of time?

A: Yes, you can prepare the sauce up to 2 days in advance. Store it in an airtight container in the refrigerator. Reheat it gently over low heat, stirring occasionally, and add a splash of water or cream if it has thickened too much.

Q: Are there other herbs I can use instead of tarragon?

A: If you don’t have tarragon, you can substitute it with fresh parsley, dill, or chives for a slightly different flavor profile. However, tarragon’s unique anise-like flavor is part of what makes this dish special.

Q: What are some good side dishes to serve with this recipe?

A: This dish pairs well with roasted vegetables like carrots or Brussels sprouts, a side of creamy mashed potatoes, or a light green salad with a tangy vinaigrette. For a more filling meal, you could also serve it with quinoa or wild rice.
